Hondata

Hello I'm tuning a K20 with nitrous, everything is wired like Hondata diagram but I have no output signal from the ECU to the relay. I'm using pin E20 for the output.
I already checked continuity from ECU wire to the relay and it's ok. On the relay all the wires are well connected.

Btw arming input (I'm using E29) is working fine.

Anyone had this problem before?

Thanks in advance

What is the ECU part number on the white plug inside the ECU?

Thanks for the reply the numbers inside the ECU are: 37820-PRA-E11 and 964547-2Y23

Please see the help file: http://www.hondata.com/help/kmanager/ni ... ub=nitrous

Not all ECUs will have the circuitry for all the outputs listed to work.

Ok I will try another output. Do you know on this particular ECU a possible output I could use?

Thanks

It should have ac clutch and fan control outputs.

I will have a try. Thanks very much

I used fan control output and it works, thanks very much for the help.
